“…It has excellent chemical stability with inverse spinel structured, which have found a number of modern technological applications in microwave devices, catalysis, adsorption, gas and humidity sensor, ferrofluid technology, fuel cells, magnetic core of coils and also used in an inorganic pigment [11][12][13]. Aono et al [14] found that MgFe 2 O 4 has the highest heating ability compare to other commercial ferrite powders of MFe 2 O 4 (M = Mg, Mn, Fe, Co, Ni, Cu and Sr) in alternating magnetic field which is one of the interesting applications in hyperthermia therapy. In addition, these MgFe 2 O 4 nanoparticles would be suitable for the use in the human body, because the elements present in these material are nontoxic [15].…”
